Abstract

Insights

Nintedanib treatment interruptions are common in systemic sclerosis-associated interstitial lung disease (SSc-ILD) patients, particularly older individuals and those with low BMI. Close monitoring and supportive care are crucial for managing side effects and maintaining treatment continuity.

Area of Science:

  • Pulmonology
  • Rheumatology
  • Pharmacology

Background:

  • Nintedanib is approved for systemic sclerosis-associated interstitial lung disease (SSc-ILD).
  • Tolerability and treatment interruptions are potential concerns in SSc-ILD patients receiving nintedanib.

Purpose of the Study:

  • To evaluate the tolerability of nintedanib in SSc-ILD patients.
  • To identify factors associated with treatment interruptions and permanent discontinuation.

Main Methods:

  • A multicentre study involving 63 SSc-ILD patients treated with nintedanib.
  • Analysis of treatment interruptions, reasons for interruption, and time to first interruption using logistic and Cox regression.
  • Comparison of weight changes before and after nintedanib initiation.

Main Results:

  • 51% of patients experienced nintedanib interruptions, most commonly due to diarrhea, nausea/vomiting, and weight loss.
  • Older age and a body mass index (BMI) <18.5 kg/m2 were independently associated with treatment interruptions.
  • Permanent discontinuation occurred in 20.6% of patients, with no significant predictors identified.
  • Significant weight loss was observed after nintedanib initiation compared to the period before treatment.

Conclusions:

  • Adverse effects frequently lead to nintedanib treatment interruptions in SSc-ILD patients.
  • Older age and lower BMI predict treatment interruptions, emphasizing the need for individualized management.
  • Most patients can resume nintedanib, underscoring the importance of supportive care for side effect management and treatment adherence.

Treatment for Pulmonary Arterial Hypertension: Endothelin Receptor Antagonists

Endothelins (ETs) are potent vasoactive peptides critical in the human body's various physiological and pathological processes. One of the most promising therapeutic strategies for treating pulmonary arterial hypertension (PAH) involves counteracting the effects of these endothelins using a class of drugs known as endothelin receptor antagonists.
ETs are synthesized through a complex sequence of enzymatic steps, primarily involving an enzyme referred to as endothelin-converting enzyme...

Bioavailability studies are essential for evaluating a drug's therapeutic efficacy and understanding its absorption patterns under various physiological conditions. Conducting such studies on target patient populations provides more relevant data by simulating real-world disease states. However, practical challenges often necessitate the use of young, healthy adult volunteers as study subjects.Patients may exhibit altered drug absorption patterns due to the effects of the disease itself,...

Therapeutic Drug Monitoring: Affecting Factors

Therapeutic Drug Monitoring (TDM) is the clinical practice of measuring specific drug levels in a patient's blood or body tissues to manage and optimize therapy. TDM is crucial for drugs with narrow therapeutic windows, like warfarin and phenytoin, where incorrect doses can lead to treatment failure or severe side effects. This monitoring ensures the dosage administered is within a safe and effective range. The factors affecting therapeutic drug monitoring include:Patient-Specific Factors:a.
